Federal prosecutors plan to include allegations related to Tampa contractor Brian Marshall’s lavish lifestyle, threats to witnesses, misrepresentations to a bank and his pressure to falsely inflate revenue as evidence in his securities fraud trial.

In a court filing on July 15, government lawyers laid out part of their case in a notice of intent to offer certain evidence.

Marshall, owner of now-defunct Fireline Restoration Inc. in Tampa and several other companies that were liquidated in bankruptcy court, faces two counts of securities fraud in an indictment related to Home Solutions of America Inc., a publicly traded company formerly based in Texas.

Fireline was a HSOA subsidiary, and Marshall was executive vice president of HSOA in 2007, when he made material misrepresentations in two fraudulent quarterly reports filed with the U.S. Securities and Exchange Commission, an indictment alleges.

Prosecutors want to show motive, intent, knowledge and planning in Marshall’s “efforts to mislead the public,” the notice regarding evidence states.

The notice accuses Marshall of threatening the life of the president of a HSOA subsidiary, Scott Sewell, who reported accounting problems to the FBI and the company’s audit committee, triggering an investigation.

Sewell is expected to testify that Marshall told him, “This is your a--.”

Marshall also is accused of falsely reporting receivables to a Texas bank that had provided a credit facility to Fireline and HSOA.

In addition, when HSOA acquired Fireline, it was not disclosed as a related-party transaction that HSOA was paying Marshall $75,000 a month to lease his private plane, the notice alleges.

Prosecutors also expect to use testimony from a controller at an HSOA subsidiary alleging that Marshall pressured him to improperly recognize revenue.

Marshall’s lifestyle, which has included gambling in Las Vegas, luxury cars and yachts, will be explored at the Nov. 13 trial.

“The government anticipates testimony from a number of government witnesses regarding Marshall’s lavish lifestyle and excessive spending during the time period described in the indictment,” the notice states.
